Product DescriptionProduct DescriptionWeifang HoTa New Material Technology Co., Ltd. specializes in the research and development and production of suspension-process polyvinyl chloride resins. It is a professional raw material supplier integrating production, sales, and technical services. The suspension process is currently the most mainstream and widely used PVC production process globally. Its mature technology, stable product quality, and wide range of applications have earned it a dominant position in the global PVC market.Our suspension-process PVC resins are based on high-quality raw materials, employ advanced polymerization processes, and undergo rigorous quality control. These products feature uniform particle size, high purity, low impurity content, strong thermal stability, and excellent mechanical properties. These properties ensure excellent melt flowability, high thermal decomposition temperature, strong color stability, and a wide processing window during subsequent processing, providing customers with outstanding production efficiency and product performance. As a customer-centric raw material supplier, we not only provide high-quality PVC resin products but also offer value-added services such as technical support, formulation optimization, and process consulting to help customers improve the performance and competitiveness of their end products. We are committed to becoming a trusted long-term partner of the global PVC industry, working with our customers to promote industry upgrading and sustainable development.SpecificationParameterSG3SG5SG7SG8StandardGB5761-1993GB5761-1993GB5761-1993GB5761-1993K-Value72–7166–6862–6059–55Polymerizing Index1300 ± 501000 ± 50800 ± 50700 ± 50Number of impurity particles (≤)16162020Volatile content (incl. water) % ≤0.30.40.40.4Apparent density (≥)0.420.480.480.50Particle size ≥0.25mm % ≤2222Particle size ≥0.063mm % ≥95959595Number of Fish Eye (1400 cm2) (≤)20203030Plasticizer absorption of 100g resin (≥)26191222Whiteness (160°C, after 10 min.) % ≥78787575VCM Residue PPM (≤)5555ApplicationThe SG3, SG5, SG7, and SG8 PVC resin grades establish a well-defined application segmentation system based on their degree of polymerization differences.1. SG3 (DP 1300-1500) specializes in high-end rigid products, with typical applications including chemical-resistant pipes, high-strength sheets, and medical transparent tubes. Its molecular weight of 95,000-110,000 endows the material with exceptional mechanical strength (tensile strength 40-60MPa) and corrosion resistance, though it requires high-temperature/high-pressure processing at 185-205°C.2. SG5 (DP 1000-1100) serves as a general-purpose rigid resin, widely used in building drainage pipes, window profiles, and electrical conduits. While maintaining structural stability from its 75,000-85,000 molecular weight, it achieves optimal balance between processability and mechanical properties through optimized melt flow index (MFI 5-8g/10min).3. The flexible applications domain is dominated by SG7 (DP 700-800). With its DOP absorption rate of 25-32%, this grade becomes the preferred material for shoe soles, synthetic leather, and cable jackets. Its designed molecular weight of 55,000-65,000 ensures efficient plastification can be achieved in the medium temperature range of 165-185°C.4. Ultra-flexible products are exclusively served by SG8 (DP 500-600). Featuring a low molecular weight structure of 40,000-50,000 and plasticizer absorption capacity of 30-38%, this grade enables rapid molding of disposable gloves, packaging films and other products at low temperatures (155-175°C), with unit production costs 15-20% lower than SG7.Key performance gradients show systematic variations:Molecular weight decreases progressively from SG3 to SG8, creating an inverse relationship between mechanical strength degradation and flow characteristics improvementProcessing temperature windows shift downward by 80-100°C with notable energy consumption differencesPlasticizer demand shows positive correlation with material flexibility, with SG7/SG8 absorption rates reaching 2-3 times that of SG3Selection matrix recommendations:Standard rigid products: Prioritize SG5 (optimal cost-performance solution)Flexible applications: Designate SG7 (surface gloss ≥85GU)Special conditions:? 6MPa-rated pressure pipes: Must use SG3 (burst pressure ≥12MPa)? Sub-0.1mm ultra-thin films: Requires SG8 (minimum extrusion thickness 0.05mm)Company ProfileWeifang Phoenix New Material Co., Ltd. is a modern high-tech chemical enterprise that integrates research and development, production, sales, and technical services.
